Free to play: three worlds, 60 puzzles, and a new Daily Rule every day. One optional unlock opens the other six worlds, Endless, and every rule you have found. You are shown two or three examples. Something happens in each of them — the same thing, every time. Nobody tells you what. Then you are shown one more, unfinished, and four ways it could end. Only one of them follows the rule. That is the whole game. No timers, no lives, no streaks, no penalty for being wrong. Just the quiet moment where you see it. NINE WORLDS, 240 HANDMADE PUZZLES CHANGE — things become other things POSITION — where something sits is the message COUNT — how many is the answer DIRECTION — orientation carries meaning INSIDE — what contains what MIRROR — reflection and symmetry SEQUENCE — order that keeps going RULES — two rules at once EXCEPTION — a rule can leave something out Each world takes one idea and goes as far as that idea can go. EVERY PUZZLE IS PROVED Before a puzzle reaches you it is tested against a catalogue of 556 rival rules. If any of them explains the same examples while pointing at a different answer, the puzzle is not shipped. That is why a hard puzzle here is never a guess: there is exactly one answer you can defend, and when you see it you will know. A NEW RULE EVERY DAY One Daily Rule, the same for everyone, free forever — whether or not you ever buy anything. ENDLESS Puzzles built on your own phone and proved by the same code before you see them, for as long as you want them. No two runs are alike. A HINT THAT DOES NOT SOLVE IT Every puzzle has one hint. It tells you where to look, never what to think. Hints are free everywhere, and using one takes nothing away from you. NOTHING TO INTERRUPT YOU No ads. No account. No sign-in. No notifications. No timer, no score, no rank, no leaderboard, no streak to protect. Nothing is collected about you, and there is no server to collect it. The whole game works offline. WHAT IS FREE, AND WHAT IS NOT Free: the first three worlds — 60 puzzles — the Daily Rule, and every hint. One payment, once, opens the rest: the remaining six worlds and their 180 puzzles, Endless, the archive of every rule you have discovered, and the full statistics. No subscription. Nothing else to buy, ever. IF YOU BOUGHT RULE BEFORE IT WAS FREE You keep everything, automatically, with nothing to restore and nothing to pay. It is already yours. Built for VoiceOver and for every text size, from the smallest to the largest.
